[0029] In this embodiment of the invention, to prevent material blockage, the anti-blocking component 6 specifically includes a motor 61 and an arc-shaped component 63. The motor 61 is fixedly connected to the outer wall of the feed inlet 31, and the output shaft of the motor 61 is fixedly connected to a rotating shaft 62, which is rotatably connected to the inner wall of the feed inlet 31. The arc-shaped component 63 is fixedly connected to the outer wall of the rotating shaft 62, and a groove is provided on the arc-shaped component 63. The rotation of the output shaft of the motor 61 drives the rotating shaft 62 to rotate, causing the arc-shaped component 63 to rotate. As the arc-shaped component 63 rotates, the groove design on the arc-shaped component 63 can guide the material to move towards the bottom of the feed inlet 31, preventing material blockage and facilitating the material to enter the screening chamber 3. This fundamentally avoids the accumulation and blockage of material at the feed inlet 31, ensuring that the material can continuously and stably enter the screening chamber 3.

The fixed plate 67 and the support 611 are both fixedly connected to the outer wall of the screening chamber 3. The eccentric wheel 64 is driven to rotate through the rotating shaft 62. Under the action of the return spring, the horizontal plate 65 moves up and down, driving the vertical rod 66 to move up and down, so that the round rod 68 slides in the straight groove 69. The swing rod 610 rotates around the hinge point of the support 611, so that the elastic ball 612 can knock and vibrate the screen plate 4 to assist in the screening of materials.

[0031] Furthermore, the adjustment component 2 includes a connecting frame 21, which is hinged to the frame 1. An electric telescopic rod 22 is hinged to the lower side of the connecting frame 21. The sleeve of the electric telescopic rod 22 is hinged to the frame 1. A guide plate 23 is fixedly connected to the outer wall of the connecting frame 21, and the guide plate 23 slides against the outer wall of the frame 1. By activating the electric telescopic rod 22, the connecting frame 21 can be rotated around its hinge point, flexibly adjusting the inclination of the connecting frame 21, thereby changing the inclination angle of the screening chamber 3. It can be adjusted according to the characteristics and screening requirements of different materials, and is suitable for screening different materials.

[0034] In use, the material is first added to the feed inlet 31. At the same time, the motor 61 is started. The output shaft of the motor 61 rotates, driving the rotating shaft 62 to rotate, causing the arc-shaped part 63 to rotate. As the arc-shaped part 63 rotates, the groove design on the arc-shaped part 63 can guide the material to move towards the bottom of the feed inlet 31, preventing material blockage and facilitating the material to enter the screening chamber 3. At the same time, the rotating shaft 62 drives the eccentric wheel 64 to rotate. Under the action of the return spring, the horizontal plate 65 moves up and down, driving the vertical rod 66 to move up and down, causing the round rod 68 to slide in the straight groove 69.
